    Abstract: In one example in accordance with the present disclosure, a computing device is provided. The computing device includes an interface module and a power management module. The interface module is to provide a user interface that facilitates enabling and disabling of an always on feature, and further facilitates configuration of a permissible advanced configuration and power interface (ACPI) S3 state period. The power management module to receive a request to enter an ACPI S3 state, determine whether the always on feature is enabled, and in response to determining that the always on feature is enabled, determine whether the computing device is within a user-defined permissible ACPI S3 state period. In response to determining that the computing device is within the user-defined permissible ACPI S3 state period, the power management module is to set a wake event and cause the computing device to enter the ACPI S3 state.

    Abstract: Examples of an apparatus, method, and instructions included on a machine-readable non-transitory storage medium are disclosed herein. In an example of the method, a first state is provided to enable a camera to record an image, a second state is provided to disable the camera, and a third state is provided to permit the camera to be enabled and disabled. Also in this example of the method, a button is actuated in the third state to an on position to enable the camera to record an image or an off position to disable the camera. Additionally in this example of the method, a signal is generated via an input device in the on position of the button to enable the camera to record an image or disable the camera.

    Abstract: Example systems relate to power monitoring and reduction processes. An example system may include a modular computing device including a plurality of universal serial bus (USB) ports and a power supply unit coupled to the modular computing device. The example system may further include an embedded controller coupled to the power supply unit and to the plurality of USB port. The embedded controller may monitor a level of power consumed by the system and determine whether a surge event has occurred in the system. In response to the determination that the surge event has occurred, the embedded controller may determine whether an agency event has occurred in the system and initiate a power reduction process in response to the determination.

    Abstract: Example implementations relate to dual rail circuitry using FET pairs. For example, a circuit according to the present disclosure may include a first field-effect transistor (FET) pair coupled to a dual rail circuitry, a second FET pair coupled to the dual rail circuitry, and a controller coupled to the first FET pair and the second FET pair. The controller may switch a power supply to the dual rail circuitry using the first FET pair and the second FET pair. The dual rail circuitry may provide a power supply to a computing device from a first power supply coupled to the first FET pair or a second power supply coupled to the second FET pair.

    Abstract: Example implementations relate to balancing a power load among USB ports. For example, an apparatus according to the present disclosure, may include a plurality of USB ports, and an embedded controller coupled to the plurality of USB ports. The embedded controller may determine that a first device is coupled to a USB port of the plurality of USB ports, and determine a power draw of the first device relative to a type of the USB port. The embedded controller may balance a power load among a remainder of the plurality of USB ports based on the power draw of the first device relative to the type of the USB port.
